Q how does turbofan engine work

A turbofan engine works by combining air propulsion with turbine technology. Air enters through the front fan, getting divided into two streams: one flows into the core, while the other bypasses it, contributing to thrust with less noise and better fuel efficiency. In the core, air is compressed, mixed with fuel, and ignited, propelling the aircraft forward. The high-speed exhaust from the combustion process further drives the turbine and the front fan, enhancing thrust. This balance between bypassed air and core process efficiency makes turbofans the go-to power plant for modern commercial airliners, offering an optimal blend of speed, fuel economy, and reduced noise levels.

Q what is a 4 rotor engine

A 4 rotor engine, often associated with the brand Mazda, is a type of rotary (or Wankel) engine featuring four rotors. Unlike traditional piston engines, rotary engines use a design that allows for smoother power delivery and compact size, owing to a spinning triangular rotor that converts pressure into rotational motion. This configuration grants the engine a high power-to-weight ratio, making it ideal for performance vehicles. Mazda’s RX-series famously utilized this engine, showcasing its ability to produce significant horsepower while maintaining a lightweight profile. However, despite its advantages in performance, the 4 rotor engine faces challenges such as lower fuel efficiency and higher emissions compared to modern piston engines, limiting its widespread adoption. Still, it remains a marvel of engineering, celebrated in motorsports and by car enthusiasts for its unique sound and performance characteristics.

Q what is engine stroke and bore

In an internal combustion engine, the terms “stroke” and “bore” are critical to understanding its design and function. The “bore” is the diameter of the cylindrical space (the cylinder) in which a piston moves. It’s a key factor in determining the engine’s displacement, or total volume of air/fuel mixture an engine can draw in a single cycle; larger bores can accommodate more air and fuel, potentially offering more power. The “stroke,” on the other hand, refers to the distance the piston travels from its highest point, or top dead center (TDC), to its lowest point, or bottom dead center (BDC). Engines are often characterized by their bore and stroke measurements which contribute to their “engine configuration.” This ratio can indicate whether an engine is designed for more power (longer stroke) or higher speed (larger bore). In essence, the interplay of bore and stroke defines much of an engine’s character, a...
